I think the lifting body one that is a seaplane is a good idea. Also, the
Russian design has some advantages.
If it was a seaplane, and launched and landed at sea, what with water covering
most of the planet, there would be more open launch paths. At the same time,
the things to launch are not necessarily at sea.
A reusable space plane is a good thing to have, as the space shuttles have shown
us. It is good that this kind of competition encourages development of the
technology to support reusable spaceplanes. Then, it is a matter of finding
which vendors produce all this technology in its various deployments.
For inert cargo like bulk raw materials, it might be more economical to use a
relative scale mass accelerometer to launch it like a cannon into orbit. That
is, it would have ground launch assist like a catapult. Far enough away, by the
other planets, there are more raw materials.
